HYDROCARBON-BURNER AND PRESSURE DEVICE THEREFOR.

SPECIFICATION formingpart of Letters Patent No. 658,794, dated October 2, 1900.

Application filed October 21, 1899. Serial No. 734.380. (N0 model.)

To all whom it may concern.-

Be it known that I, GUSTAVE A. LOEBEN, a subject of the Emperor of Germany, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Hydrocarbon-Burners and Pressure Devices Therefor,

of which the following is a specification.

The main object of my invention is to produce the pressure necessary for forcing the hydrocarbon or other fluid to be vaporized or gasified by means of a fixed gas under pressuresuch, for instance, as ordinary illuminating-gasand to regulate this pressure.

A further object of the invention is to provide a tank or supplemental reservoir from which the fluid will flow automatically when the pressure in the main reservoir is reduced. A still further object of the invention is to heat the burner by the gas used for creating pressure in the reservoir.

In the accompanying drawings, Figure 1 is a side view of my improved apparatus. Fig. 2 is an enlarged sectional view of the main reservoir and regulator, and Fig. 3 is a view of a modified form of valve used in the burnersupply pipe.

A is the main reservoir, and B is the tank or supplementary reservoir, having a fillingopening 17, which is provided with a screw plug or cap. The supplementary reservoir is connected to the bottom of the main reservoir A through a pipe I), and in the bottom of the said reservoir A is a check-valve b opening inward, so as to allow for the free flow of fluid from the supplemental reservoir B into the main reservoir A, but preventing the escape of fluid through this pipe from the reservoir A. g

D is a container for fixed gas under pressure. either used for heating or illuminating. The container can be charged in any suitable manner.

E is a diaphragm-regulator, having a diaphragm e, and projecting from the diaphragm diaphragm in the regulator is connected to This gas may be the ordinary gas the upper portion of the reservoir A through a pipe 61, being coupled to a fitting (1 in which is a valve-seat 01 f is a valve adapted to the seat (i The stem f of this valve has a slot f in which works a pin g on the stem G, extending from top to bottom of the reservoir A. This stem has a flange or collar 9, against which strikes a float H when it is raised to its full limit.

Connected to the bottom of the reservoir A is a pipe 0}, communicating with the lamp I, which may be of any of the ordinary forms of vapor-lamps in which oil or other burning fluid is vaporized or gasified.

In the bottom of the reservoir A is a valveseat a, and in the end of the stem G is a valve which is adapted to close upon the seat a. On each side of the stem are two or more instance to the bottom of the casing of the reservoir, and these springs hold the stem G in its raised position, resting under a shoulder 9 on the stem, as shown in Fig. 2.

On the under side of the float H is a projection h, which when the float is lowered comes in contact with the springs and forces them away from the stem,"c ausing the stem to fall, so that the valve 9 will rest upon its seat a and close the passage leading from the reservoir and also seating the valve f, closing the passage leading from the regulator. This occurs when the burning fluid in the reservoir A is at such a point that the reservoir A needs replenishing.

Communicating with the upper portion of the reservoir A is a pipe k, which also leads to the lamp 1. This pipe is for the purpose of conveying the heating or illuminating gas that is used for pressure to the burner for the preliminary heating of the burner.

The pipe I is provided with a valve 2', and the pipe K is provided with a valve is. c is a by-pass forming acommunication bet-ween the pipes lo and 'i, and in the passage 0 is a valve 0'.

The operation of the apparatus is as fol.- lows: The reservoirs are so proportioned that a certain amount of burning fluid will be used for a certain number of hours. The tank B is filled with burning fluid and the reservoir D is charged with gas under pressure, the

as this pressure is reduced the fluid fromthe tank 13 will open the check-valve b and flow into the reservoir A by gravity, thus causing the float H to be raised. This float will becarried by the incoming fluid until it strikes the flange g on the stem G, when itwill raise the stem, causing the valve 9 to be raised from its seat and also raising the valvef from its seat. Thus the desiredpressure is immediately placed upon the fluid in the reservoir A from the container D, and this pressure being greater than the pressure of the incoming fluid from the tank B causes the check.- valve to close automatically. The valve is then closed and the valve t" in. the pipe I opened, allowing the fluid from the reservoir A to be forced up into the lamp I. The lamp, being previously heated by the ignition of the gas, vaporizes or gasifles the fluid. As the 1 float lowers the above operation will be repeated.

.In some instances it may be necessary to feed the oil direct from the reservoir B to the lamp, and in this case the valve 0 in the bypass 0 is opened, so that there is direct com.- muuication between the pipes b and 2'.

A three-way valve may be used, as shown in Fig. 3, in place of the two valves i and k, and a single pipe connected to the burner.

The details of construction may be varied without departing from the main object of my invention.

I claim as my invention- 1. The combination of the reservoir, means for admitting gas to the reservoir, a burner communicating with both the upper andlower portions of the reservoir, and means for antomatically closing the passage leading from the bottom of the reservoir when the fluidlin the reservoir is low, and means for regulating the flow of gas to the upper portion of the reservoir, substantially as described.

2. The combination of the reservoir, a con.- tainer for gas under pressure, apassage forming a communication between the container and the upper portion of the reservoir, a regulater in the passage, a burner communicating with the bottom of the reservoir, a tank also communicating with the reservoir, a checkval've for allowing the flow of fluid from the tank into the reservoir, and means for preventing the admission of gas under pressure when ,the fluid in the reservoir is low and also preventing" the escape of fluid fromthe reservoir to the-lamp when the fluid in the reservoir is low, and an escape for gas under pressure so that when the pressure in the reservoir is reduced fluid will automatically flow from the tank into the reservoir, substantially as described. 7

32 The combination of a reservoir, a tank :situated above the reservoir, a pipe forming communication with the tank and with the y the container totheupper portion of the reservoir, a regulator in said; pipe for reducing the pressure,.a pipe leading from the bottom of the reservoir to the burner, a float in'the reservoir, and valves for closing the passagev leading. from. thecontainer and fromthe reservoir to the lamp, said valves beingactuated by the float, substantially as described.

4. The combination of a reservoir, a container. for gas under pressure,.a pipe leading from the, container to the reservoir, a regulator in said. pipe,.a burner, a pipe leading fronrthe bottomof the reservoir to the burner, apipe leading from the top of. the reservoir to the burner, valves in said pipes, a float within the reservoir, and means actuated by said float when the liquid is low in the reservoir to close the outlet from the-bottom of the tank to the lamp and-the inlet from the gascontainer, substantially as described.

5. The combination of areservoir, a burner communicating with the bottom of the reservoir and connected independently with the top of the reservoir atank mounted above the reservoir and com m unicati n gwith the bottom of the reservoir,,a valve in said pipe, a by-pass connecting the pipe leadingfrom the tankwith. the pipe leading from the reservoir of the burner, and: a valve in said by-pass, substantially as-described.
